Working while receiving SSDI isn't forbidden — but it's tightly regulated. The Social Security Administration uses specific income thresholds to determine whether your work activity is significant enough to affect your benefits. Understanding those thresholds, and the rules surrounding them, is essential for anyone receiving SSDI who wants to work or is already working.
The SSA measures work through a standard called Substantial Gainful Activity (SGA). If your earnings exceed the SGA threshold, the SSA may determine you're capable of supporting yourself through work — which can trigger a review of your eligibility.
In 2025, the SGA limits are:
| Category | Monthly Earnings Limit (2025) |
|---|---|
| Non-blind SSDI recipients | $1,620/month |
| Blind SSDI recipients | $2,700/month |
These figures adjust annually, typically alongside cost-of-living adjustments (COLAs). The blind threshold is higher because the SSA has historically recognized the greater employment barriers faced by people with blindness.
Earning above these amounts doesn't automatically end your benefits immediately — but it does set the SSA's evaluation process in motion.
Before the SGA limit becomes fully binding, most SSDI recipients get a Trial Work Period (TWP). This is a nine-month window (which doesn't need to be consecutive) during which you can test your ability to work without losing benefits, regardless of how much you earn.
In 2025, a month counts as a trial work month when you earn more than $1,110. Once you've used all nine trial work months within a rolling 60-month window, the SGA threshold kicks in.
This structure matters because it separates two different questions:
After your trial work period ends, you enter a 36-month Extended Period of Eligibility (EPE). During this window, any month in which your earnings fall below the SGA threshold, you remain entitled to receive your full SSDI payment — without reapplying.
This means a period of higher earnings doesn't permanently sever your benefits if your income later drops. The EPE functions as a safety net beneath the trial work period.
The SSA doesn't just look at your gross paycheck. Countable earned income for SGA purposes can be adjusted for certain factors:
These adjustments mean two people earning the same gross income can have very different countable earnings under SGA rules.
If your earnings consistently exceed the SGA threshold after your trial work period and extended period of eligibility have run out, the SSA will likely find that you are no longer disabled for SSDI purposes. This is called a cessation of benefits.
However, this isn't instantaneous. The SSA typically allows a grace period of three full months of SGA-level earnings before stopping payments. And if benefits do stop, the Ticket to Work program may provide additional protections and return-to-work support.
The SGA threshold is a fixed number, but how it interacts with your situation depends on several factors:
A person early in their SSDI benefits who has not yet used any trial work months operates under very different rules than someone who exhausted their TWP three years ago and is now in a periodic CDR.
The SGA threshold is a line on paper. Whether your specific earnings, work arrangement, and disability expenses put you above or below that line — in a way that actually affects your benefits — depends on how the SSA evaluates your particular work activity, what documentation you've provided, and where you are in the benefit timeline.
Those calculations aren't ones the numbers alone can answer.
